Upload a File

Now that you have a bucket to put files in, you are ready to upload a file.

List buckets will show you the bucket ID you need to upload files:

$ b2 list_buckets
10f72c8d00b1ea614ceb0319 allPublic KittenPhotos

If you have a local file on your computer called "kitten.jpg" and you want to upload this file to your "KittenPhotos" bucket into a folder named "fluffy", you would do it like this:

$ b2 upload_file KittenPhotos kitten.jpg fluffy/kitten.jpg
URL by file name: https://f004.backblazeb2.com/file/KittenPhotos/fluffy/kitten.jpg
URL by fileId: https://f004.backblazeb2.com/b2api/v2/b2_download_file_by_id?fileId=4_ze1256f0973908bfc71ed0c1z_f10072d5b729d51d1_d20150731_m214727_c100_v0009990_t0004

    "fileInfo": {}, 
    "fileName": "fluffy/kitten.jpg"

The ls command will show the files in your bucket:

$ b2 ls KittenPhotos
